Fabrication and performance of low-fouling UF membranes for 2 the treatment of Isolated Soy Protein solutions
[EN] Consumers are becoming more conscious about the need to include functional and nutritional foods in their diet. This has increased the demand for food extracts rich in proteins and peptides with physiological effects that are used within the food and pharmaceutical industries. Among these protein extracts, soy protein and its derivatives are highlighted. Isolated soy protein (ISP) presents a protein content of at least 90%. Wastewaters generated during the production process contain small proteins (8-50 kDa), and it would be desirable to find a recovery treatment for these compounds. Ultrafiltration membranes (UF) are used for the fractionation and concentration of protein solutions. By the appropriate selection of the membrane pore size, larger soy proteins are retained and concentrated while carbohydrates and minerals are mostly recovered in the permeate. The accumulation and concentration of macromolecules in the proximity of the membrane surface generates one of the most important limitations inherent to the membrane technologies. In this work, three UF membranes based on polyethersulfone (PES) were fabricated. In two of them, polyethylene glycol (PEG) was added in their formulation to be used as a fouling prevention. The membrane fouling was evaluated by the study of flux decline models based on Hermia's mechanisms.The Universitat Politecnica de Valencia (Spain), through the project 2623 (PAID-05-10), funded this research.Garcia-Castello, EM.; Rodríguez López, AD.; Barredo Damas, S.; Iborra Clar, A.; Pascual-Garrido, J.; Iborra-Clar, MI.

Evaluación de micro innovaciones para la mejora continua de la asignatura Tecnología Medioambiental
[ES] Esta comunicación reflexiona sobre la introducción de micro innovaciones en la asignatura Tecnología Medioambiental del Grado en Ingeniería Mecánica en la Escuela Técnica Superior de Ingeniería del Diseño de la Universitat Politècnica de València. La estrategia innovadora responde a las tendencias del empleo de las nuevas tecnologías, la creación comunicativa de contenidos y la interdependencia en el aprendizaje. Se explica la realización de documentación multimedia por parte de los estudiantes como metodología docente, incluyendo actividades de evaluación por pares. Consideramos que es adecuada para el desarrollo de la competencia transversal “Conocimiento del mundo contemporáneo”, mediante la búsqueda de nuevos conocimientos y la exposición y crítica de los trabajos realizados. Se detalla la investigación realizada para poder mejorar y escalar dichas micro innovaciones.[EN] This paper presents some micro innovations in Environmental Technology, a subject of the Mechanical Engineering Degree of the Universitat Politècnica de València. The innovative strategy responds to the trends of the use of ICT, the technical communication skills and the interdependent learning.Multimedia content creation from students as a part of the teaching methodology, and peer evaluation are presented. Adequacy to development of the transversal competence “Contemporary world understanding” is considered, through desk research, critical thinking and exhibition of the outcomes.In order to improve and scale the micro innovations, a research was conducted. Details about the research methods and results are provided.Luján Facundo, MJ.; Rodríguez López, AD.; Ferrer Polonio, E.; Laguarda Miró, N.; Pascual Garrido, J.; Fuentes-Durá, P. (2021).
